I am kicking around getting into an AirBNB, but I haven't quite made the decision yet. I really like the idea of being able to spread out in a house or an apartment. There are several in the area of the convention center priced less than the area hotels. Does anyone have an opinion of one of these as compared to a hotel?

I have not stayed at an AirBNB in Austin, however, I would highly recommend it! It's the only way we travel these days.

Just make sure there's good reviews of course and check out the pics. You'll probably want to search for a private house/apartment not a private room - could wake the owners at the hour you'll be getting back! ;)
